Summary: The TomTom XXL 540 S improves on the TomTom XL line by keeping the features we love while improving screen visibility; but the bigger size comes with compromised portability.
Pros: The TomTom XXL 540 S has advanced features such as lane guidance and user-updated maps from TomTom Map Share. Its huge 5-inch touch screen is easy to read and to input addresses. Text-to-speech enhances the device's safety.
Cons: With a wide 5-inch screen and a thick EasyPort mount, pocketability goes out of the window. Routing from a moving vehicle is considerably slower than from a stationary one.
